In a remarkable moment after WWII New York became the centre of the art world, simultaneously seeing the development of new ways of hearing music, and new ways of seeing art.

"For the next hour, I need your ears". It's 1974 and someone is trying to recruit you for a listening experiment on public radio in Canada.

Pioneering Canadian composer and soundscape maestro, R Murray Schafer really wants you to commit: "if you're just listening to this programme casually, you'd better turn it off right now".

This audio experiment was part of a series on the CBC - the Canadian Broadcasting Company, called Soundscapes of Canada, consisting of ten hours of soundscape montage, field recordings and lessons in listening. From Church bells, to birdsong, to car horns and an entire episode made up of people across Canada giving the sound recordist directions: this was 'slow radio' years ahead of its time.

The series was recorded and produced by The World Soundscape Project, a group Schafer set up to raise the importance of the soundscape in what he saw as a world of increasing noise, which had reached "an apex of vulgarity". The group went on to publish Soundscape: The Tuning of the World - a vast anthology documenting just about every kind of sound you could imagine - natural, human-made and technological.

R Murray Schafer was many things – Canada’s preeminent experimental composer of the 20th Century, an artist, novelist, educator, musicologist, historian, and environmental activist. Schafer was also a romantic, with a strong sense of Canadian identity, who preferred rural life with an uncluttered sense of place. Critics, and he had many, accused him of being abrasive, a luddite, and prone to cultural appropriation.

Above all though, Murray was a passionate listener, constantly pushing his message of an "ecologically balanced soundscape" by asking "which sounds do we want to preserve, encourage, multiply?" In this sound-rich documentary (best enjoyed with headphones) John Drever, Professor of Acoustic Ecology and Sound Art at Goldsmiths, University of London explores Schafer’s life and legacy, as the soundscape now has an ISO framework for consideration in urban design and planning in the UK and beyond.

Denton Welch lived the last years of his short life in Kent during the Second World War. His writing career took off in 1943 and in the same year he met his companion, Eric Oliver.

His preoccupations include art and beauty as well as pain and death. His great ability as a writer is to draw characters - often based entirely on himself and those closest to him - with tiny details which spring to life on the page. These can be very funny, cruel, poignant or erotic.

Known in Yiddish as Der Schvartze Khazn--the Black Cantor--Thomas LaRue Jones was an African American tenor who sang Jewish music in the early decades of the twentieth century. Famed for his soulful voice and perfect Yiddish pronunciation, he performed in synagogues and theatres across the Eastern United States and toured Germany, Poland and Palestine. But after his death in 1954, LaRue Jones disappeared from memory, leaving behind only one recording, made in 1923. Drawing on research by the veteran musician and producer Henry Sapoznik, Maria Margaronis unpacks the mystery of LaRue Jones' career. What drew him to this music? What does his life tell us about race, faith and identity in America a hundred years ago? And why was he so quickly and utterly forgotten?

LaRue Jones' story is entwined with the history of Newark, New Jersey, where he spent most of his life. Once known as the City of Opportunity, old Newark drew migrants from Europe and the American South in flight from persecution and searching for a new life. Blacks and Jews lived side by side in the city's poorer districts, absorbing each other's culture and musical traditions.

But by mid-century, Newark's Jews were moving out in search of the suburban dream. Black people, hemmed in by racism and housing segregation, were left behind in an increasingly impoverished city. Thirteen years after LaRue Jones' death, the Newark riots, or rebellion, sealed the division of the two communities. LaRue Jones, like the world that made him, was consigned to oblivion--until zealous research by Henry Sapoznik tracked down that one recording and LaRue Jones' unmarked grave, and raised the curtain on the Black Cantor once more.

Over a century ago, in 1881, the city of Birmingham purchased a copy of Shakespeare's first folio. It was to be the crown jewel of their new Shakespeare library, the brainchild of the first librarian George Dawson. From the outset it was to be the People's Folio, the property of the city's Free library. You can find the evidence stamped in red ink on many of the pages. That might seem like a defacement to some, but to Shakespeare scholar Islam Issa and members of the city's 'Everything to Everybody' project, it shows a profound commitment.

One day, three decades after the event, the German poet and man of letters, Heinrich Heine, stood on the site of the battle of Marengo, one of Napoleon's earliest and most important victories and had an epiphany - or he invented one for his readers: ""Gradually, day by day, foolish national prejudices are disappearing; all harsh differentiations are lost in the generality of European civilization. There are no more nations in Europe, only parties; and it is marvellous to see how these parties, for all their varying colouration recognize one another and how they understand one another, despite many differences in language."

This move past national differences would be a force for unalloyed good because, if Europeans could see themselves as a unified "civilisation" then their example would be a force that "could" lead to the liberation of the world from prejudice.

Well, he was a child of the romantic age, you can forgive his enthusiastic language but his vision anticipates the principles that created and still guide the EU.

The writer produced astounding amounts of work: poetry, verse dramas, and essays and letters while conducting love affairs and just generally being in the public eye.

His poetry became the lyrical basis for lieder by Schubert, Schumann and many others. He had huge appeal in the middle of the 19th century. George Eliot wrote four monographs about him including one on his wit - bitterly ironic ,very Jewish.

Today he is remembered in the English speaking world for this quote, "Where they burn books, they will, in the end, burn human beings too." When the Nazis held their book burnings outside the Berlin Opera House, Heine's were among those immolated. And when the Nazis initiated the war that would burn down a significant portion of the Europe Heine dreamed of, the connection to much of 19th century German culture was cut including the life and work of Heinrich Heine.

Michael Goldfarb tells the story of Heine's life and the Europe in which he lived through interviews and using the musical settings of his poetry in lieder, readings from his poetry and plays, and George Eliot's perceptive comments.

Heine's was a tremendous life - he endured censorship and was harassed by the police spies of the Federated German speaking nations. He lived as a celebrity - albeit an impecunious one - despite the fact his uncle was one of the German-speaking world's richest men. All the drama created a truly contemporary, 21st century sensibility

A Certain Height production for BBC Radio 3

American musician Rhiannon Giddens investigates the fascinating life and recordings of the folk song collector Sidney Robertson Cowell. Travelling thousands of miles all over the US in the depression era, Cowell was willing to track down songs in unlikely places, once writing "I don't scare easily." She spent a night riding in a hearse in Wisconsin just to question the driver and hear his songs, walked up mountains to record lumberjacks and traditional Appalachian singers and poled three miles downriver after dark on a makeshift raft to find a famed fiddler in his goldmine in California.

Listening to her recordings is like travelling back in time; they capture the voices of so many different nationalities that emigrated to the US, but she also made recordings on the Aran Islands in Ireland. During her lifetime Cowell was marginalised like so many women collectors of that period, but in this celebration of her recordings and observations, Giddens finally gives her work the attention it deserves.

With indebted thanks to the American Folklife Center archive in the Library of Congress who hold the collection of Sidney Robertson Cowell's recordings and to the following contributors who have done so much to bring her work to light:

Cathy Hiebert Kerst, folklorist and archivist who catalogued Sidney's recordings of the WPA California Folk Project.

Sheryl Kaskowitz, scholar of American music and author of forthcoming book: The Music Unit: FDR's Hidden New Deal Program that Tried to Save America from the Great Depression—One Song at a Time.

Jim P Leary, a folklorist and scholar of Scandinavian studies, and a professor at the University of Wisconsin–Madison, author of Folksongs of Another America.

Dr. Deirdre Ní Chonghaile writer, researcher and musician (she plays fiddle with Rhiannon at the end of the programme) who has written about the collecting work of Sidney Robertson Cowell on the Aran Islands in the 1950s.

Robert Cochrane, Professor of English and folklore specialist at the University of Arkansas.

Peggy Seeger, folksinger.
